If a speed mismatch was configured between two Cisco routers' Ethernet interfaces, what would be the status of this interface?
A) Down/down
B) Up/up
C) Up/down
D) Up/down (err-disabled)
A
Explanation: A) When a speed mismatch occurs on an Ethernet link connected to a Cisco device, the interface will be in a down/down state until the mismatch is resolved. Typically, this is not an issue because the speed is usually autoconfigured, but this problem could arise if the speeds are statically configured.
